Thanks for posting and reaching out to us today!
This isn't a feature that is built into any of our Bose Systems/Apps directly meaning that you wouldn't be able to do this via a Bose App. As far as I am aware this is something that you would be able to do via Spotify Connect as long as you are connected to the systems via this platform.
I would recommend testing this out a few times before you do go away to ensure that this works first. If you have any questions about Spotify Connect I would recommend reaching out to their support team via this link here.
I hope this helps provide you with a solution to this question and if you have any other questions please don't hesitate to reach back out to the community.
